I have a month old laptop with a fresh install that I'd performed using its WiFi connection, so I know it works. But now, the card doesn't even show-up on `lspci`. I was using the laptop, plugged-in and with Ethernet all this while. It is highly unlikely to be a hardware issue, because it was working perfectly fine, and is very new.
I'm at my wits end as to what the problem might be. Any guesses as to what the problem might be?

Yes, I do have that; and I did initially, post-install, use the laptop on WiFi for a short while.

Please post the output of the following:
uname -a
pacman -Q linux
EDIT: this is to check that the running and installed kernels are the same version - though in hindsight such a mismatch would be a common explanation for the interface not showing up in tools like `ip`, but would not explain the absence from lspci - but it's still worth checking.
Are you sure this is / was a pci card before? Have you checked the lsusb output for network/wireless devices?i

I am pretty sure it is a PCI card, because this is the laptop: https://wiki.archlinux.org/index.php/Le … AMD)_Gen_1 , and other components are the same as the `lspci` described there, as far as I can see. The only difference in my case, is the missing WiFi entry, and an extra Ethernet entry:
05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)
`lsusb` does not show any wireless or network devices.
